Efficient Key Management Scheme for Mobile IP Multicast
一种有效的移动IP组播密钥管理方案*

In this paper, we present a key management scheme that is suitable for mobile IP multicast. By localizing the delivery of rekeying messages, the communication cost is reduced. Furthermore, we consider the effect exerted by the mobility of user on the key management tree. Finally, the performance of this scheme is analyzed, showing the scheme is fairly scalable.
